[Users] usrloc, presence etc. cleanup rate: OpenSER mysql backend

[Bernard Chan]

Hello,

I would like to know how frequently OpenSER are cleaning up stale
records with the mysql backend of various modules? For instance,
active_watchers, location, presentity, watchers etc. mysql tables, or
are stale records automatically removed at all? As I found a row in the
location table with an "expires" date more than a month ago, but was
still not cleaned up today. Or OpenSER takes a different strategy?

This is because we expect to deploy OpenSER on a fairly large network
and we are estimating database size and related overhead, and we are a
bit worry that accumulation of these stale records may increase our
processing costs.

Thank you in advance for any insights.

Regards,
Bernard Chan.
